Embodiment
The view of Fig. 1 shows according to the structure of the first preferred embodiment of pressure regulator valve of the present invention.In valve chest 2 internal structure holes 1, valve piston 5 is axially movably guided in hole 1.Boot segment represents with reference character 13.Valve chest 2 has the annular accommodating chamber of the magnetic coil 20 of magnetic assembly 7 at first end, it is coaxial with hole 1 and around hole 1 that this annular accommodating chamber is configured to.Armature chamber 8 connects accommodating chamber, being contained in armature chamber 8 with the interactional armature 6 of magnetic coil 20 of magnetic assembly 7.Armature chamber 8 is surrounded by tank shape cover piece 21, thereby also forms the accommodating chamber of spring 19, and the spring force of spring 19 adds load towards 4 pairs of armature 6 of valve seat.
For shown in pressure regulator valve, the magnetic force of magnetic coil 20 is along the direction effect identical with the spring force of spring 19, thereby realizes another closing force by magnetic coil 20.In order to open described valve, the hydraulic pressure of proximate valves inlet side, the pressure in hig pressure storage device, must improve, like this so that overcome at least spring force of spring 19.The present invention also comprises pressure regulator valve, and in described pressure regulator valve, magnetic force resists spring force.
Armature 6 is connected with valve piston 5, thereby the magnetic force of the spring force of spring 19 and magnetic coil 20 applies the closing force towards valve seat 4 to armature 6 and valve piston 5, and valve piston 5 is axially movably guided in the hole 1 of valve chest 2.If magnetic coil 20 finishes energising, the pressure having raise in fuel high pressure reservoir (not shown) causes that described valve opens.Pressure reduction between inlet side pressure and outlet side pressure causes being currently constructed to spherical valve closure member 3 and rising from valve seat 4.Along with the stroke of valve enclosed member 3, valve piston 5 and armature 6 also overcome the spring force of spring 19, towards cover piece 21 motions.In this operating position, described pressure regulator valve can make described fuel high pressure reservoir be connected with low tension loop (not shown).Now, the valve inlet 15 of fuel center hole in being constructed to valve piece 16 from hig pressure storage device, valve chamber 9 and at least one radial hole 14 as valve outlet port flow out, and cause by this way the pressure drop in hig pressure storage device.Valve piece 16 is supported on valve chest 2 via space washer 17.
The present invention is actually that hole 11 by forming in valve chest 2 and throttle valve 12 realize, and hole 11 and throttle valve 12 make valve chamber 9 and armature chamber 8 hydraulic connectings.In order to form described throttle valve, hole 11 is constituted as shoulder hole, and hole 11 has the flow cross section dwindling in the region of throttle valve 12.Hole 11 or throttle valve 12 lead in the radial hole 14 that is used as valve outlet port, thereby hole 11 is connected with valve chamber 9 by radial hole 14 indirectly with throttle valve 12.In contrast, the other end in hole 11 leads in armature chamber 8, and the additional groove 10 wherein arranging in armature 6 and additional holes 11 make the inner easily pressure balance of armature chamber 8.
The hydraulic connecting of, valve chamber 9 that form by throttle valve 12, hole 11 and armature chamber 8 has expanded hydraulic volume, and the equilibrium of pressure surge or pressure wave is provided.Especially the low tension loop by connection outlet side is incorporated in valve chamber pressure surge or pressure peak are compensated or are at least attenuated, thereby guarantee the higher functional safety of pressure regulator valve.And isostasy realizes quickly.
From Fig. 2, learn the second preferred embodiment.Hole 11 and throttle valve 12 are configured in valve piston 5 in a second embodiment.Throttle valve 12 is formed into transverse holes, throttle valve 12 and hole 11 connection valve chambers 9.Correspondingly, hole 11 is directly led in valve chamber 9 via throttle valve 12.This embodiment's a remodeling is shown in Fig. 2 b.In this remodeling, throttle valve 12 is made for Zhigou, and it has the cross section that the cross section with respect to hole 11 dwindles.
From Fig. 3, learn the 3rd preferred embodiment.Hole 11 is also configured in valve piston 5, and leads in transverse holes, and hole 11 and transverse holes have identical cross section.Described transverse holes is not directly to lead in valve chamber 9, but leads in an annular space, and this annular space is formed between valve piston 5 and valve chest 2 and as boot segment 13.At least in lower area, in the region between valve chamber 9 and hole 11 or transverse holes, boot segment 13 thereby have radial clearance, produces the throttling action of wishing.
Figure 4 and 5 are learnt the embodiment closely similar with Fig. 1.Yet Fig. 4 illustrates hole 11 and is made for shoulder hole to form throttle valve 12, and Fig. 5 learns the example of the throttle valve with independent formation.
Embodiment according to Fig. 5 has illustrated corrective measure, and the concrete structure that does not rely on groove 10 and/or hole 11 and throttle valve 12 is complementally used.Thus, this measure also can individually or increase and realize in the embodiment of foregoing Fig. 1 to 4.
Figure 6 illustrates the first improved supplementary measure.Here, valve chest 2 removes 11 off-lying seas, hole and has another axial bore, yet this axial bore is made for blind hole, and additional hydraulic volume 18 is provided, and this has expanded armature chamber 8.Additional hydraulic volume 18 is not only conducive to compensation or attenuate pressure wave is moving, and the natural frequency that is conducive to simultaneously change described pressure regulator valve is to react on the natural vibration of described pressure regulator valve.
Corrective measure shown in replacement or supplementary Fig. 6, for example as shown in Figure 7, hole 11 is arranged in armature 6.The prolongation aspect in 11 hole, hole 11 is arranged in valve chest 2 or with respect to hole 11 and misplaces and arrange.Under a rear situation, a groove 10 is also preferably set on the downside of armature 6, this groove 10 connects two holes 11 (referring to Fig. 1).
If valve chamber 9 is not directly connected to low tension loop via radial hole 14, but indirectly by armature chamber 8, be connected to low tension loop, this is also favourable.In the embodiment shown in fig. 8, valve chamber 9 is connected to low tension loop by radial hole 14, throttle valve 12, hole 11 and armature chamber 8.The flow path obviously extending reacts on the propagation from the pressure surge of low tension loop.And the impact of the flow velocity of the fuel flowing out via radial hole 14 is diminished.
Fig. 9 shows another preferred embodiment of the present invention, and the difference of this embodiment and previous embodiment is that throttle valve 12 is positioned at the downstream in hole 11.Hole 11 is led in armature chamber 8 by throttle valve 12 in a side, at opposite side, by radial hole 14, leads in valve chamber 9.Here also can addedly make in conjunction with the corrective measure shown in Fig. 6 to 8.
Finally, Figure 10 shows another alternate embodiment.In this embodiment, armature 6 is configured to plug-in type armature, utilizes the spring force of spring 19 to load along opening direction.It is openable valve that described valve is correspondingly made for without energising.The hydraulic connecting of valve chamber 9 and armature chamber 8 is current to be consisted of groove 10, and groove 10 forms at the wall intermediate reach in the hole 1 of valve chest 2 with extending axially.In lower area as the hole 1 of boot segment 13, described groove has the cross section diminishing at the same time, thereby forms throttle valve 12, and throttle valve 12 makes groove 10 be connected with valve chamber 9.Corrective measure shown in Fig. 6 to 8 can be added and form, and these corrective measures are also applicable to this embodiment.
Point out below, except Fig. 1 to 10, each view is schematically described.For example, valve chest is obviously simplified, and its mode is that for example valve seat 4 and/or the view of valve inlet passage 15 and/or the different views of valve piece 16 are removed.If or obviously magnetic assembly 7 is not shown simplifiedly, this is equally applicable to magnetic assembly 7.
